These exercises and activities are for students to use independently of the teacher to practise number properties.
Addition and Subtractions, AM (Stage 7)
Prior knowledge
Use a range of number strategies for solving addition and subtraction problems with whole numbers.
Background
In this activity students solve simple algebraic equations that involve integers. It combines their ability to add and subtract integers, use a range of addition and subtraction strategies, and work with simple equations that involve an x. Students are not required to know any methods of solving equations to be able to solve these problems. The requirement is that they immediately write the equation in a form that tells them the calculation they need to do (for learning this skill with whole numbers see Task: Strategic Solving Part I). Students will be required to select an appropriate Add / Sub strategy in order to calculate x.
